Hoʻokumu ʻia ka module port serial Bluetooth ma ka Serial Port Profile (SPP), he mea hiki ke hana i kahi pilina SPP me kekahi mea Bluetooth ʻē aʻe no ka lawe ʻana i ka ʻikepili, a hoʻohana nui ʻia i nā mea uila me nā hana Bluetooth.
Ma ke ʻano he modula kamaʻilio kelepona maʻamau, loaʻa i ka module port serial Bluetooth nā hiʻohiʻona o ka hoʻomohala maʻalahi a me ka hana maʻalahi. Inā hoʻohana ka mea hana i ka module port serial Bluetooth i hoʻokomo ʻia + MCU e hoʻomohala i nā huahana me ka hana Bluetooth, hiki i nā mea hoʻomohala huahana uila / ʻenekinia ke hāʻawi maʻalahi i nā huahana uila me nā awa serial MCU me ka ʻole o ka ʻike hoʻomohala ʻoihana Bluetooth. Ua hōʻemi nui ʻia nā kumukūʻai noiʻi a me ka hoʻomohala ʻana o ka hui a me nā koina hana, akā ua hōʻemi pū kekahi i nā pilikia hoʻomohala.
Hoʻomaopopo ka module port serial Bluetooth i ka hoʻokaʻawale ʻana o ka hoʻomohala ʻana o MCU a me ka hana hoʻomohala Bluetooth, ka mea e hōʻemi nui ai i ka paʻakikī o ka hoʻomohala ʻana i ka huahana Bluetooth, hoʻomaikaʻi i ka paʻa a me ka wikiwiki o ka hoʻomohala ʻana i ka huahana, pōkole i ka pōʻai hoʻomohala huahana, a hoʻolōʻihi i ka manawa e mākeke.
Aia kekahi mau pilikia e makemake paha ʻoe e ʻike:
1. Hiki i ka Bluetooth serial port module ke hoʻouna i nā leo?
Hoʻokumu ʻia ka module port serial Bluetooth ma ka protocol Bluetooth a hoʻokō i ka SPP, ʻo ia kahi noi port serial. ʻAʻole kākoʻo ʻia nā noi ʻē aʻe e like me nā noi leo A2DP. Akā ʻo ka USB adapter Bluetooth (dongle) he mau noi like ʻole, e like me ka hoʻoili faila, ke awa serial virtual, leo a pēlā aku.
2. Pono au e hoʻomaopopo i ka protocol Bluetooth i ka wā e hoʻohana ana i ka module port serial?
ʻAʻole, e hoʻohana wale i ka module port serial Bluetooth ma ke ʻano he peripheral serial transparent. Ma hope o ka hoʻopaʻa ʻana me ka module port serial Bluetooth ma ke kamepiula a i ʻole kelepona paʻalima, hiki iā ʻoe ke wehe i ka port serial virtual Bluetooth pili a me ka module port serial Bluetooth ma o ka polokalamu noi e kamaʻilio. Hiki ke hoʻopili ʻia ka module Bluetooth i nā peripheral ʻē aʻe me kahi port serial, e like me kahi microcontroller a i ʻole kamepiula ʻē aʻe.
3. Pehea e ho'āʻo ai inā he maʻamau ka module port serial Bluetooth?
E hāʻawi mua i ka mana i ka module Bluetooth (3.3V), a laila pōkole-circuit TX a me RX, e hoʻopaʻa i ka module port serial Bluetooth ma o ke kamepiula a kelepona paha, a laila hiki iā ʻoe ke hoʻouna a loaʻa i ka ʻikepili ma o ka polokalamu port serial, no laila hiki iā ʻoe ke e ho'āʻo inā he maʻamau ka module port serial Bluetooth.
No nā kikoʻī hou aku, e ʻoluʻolu e hoʻokaʻaʻike me Feasycom Sales Team.
